A dual-motor driving device includes an input axle, a sleeve that is rotatable relative to the input axle, two rotors, a axle one-way clutch and a first rotor one-way clutch. Each of the rotors surrounds the sleeve. The axle one-way clutch is mounted between the input axle and the sleeve so that rotation of the input axle relative to the sleeve in a first rotating direction is prevented, and that rotation of the input axle relative to the sleeve in a second rotating direction opposite to the first rotating direction is permitted. The first rotor one-way clutch is mounted between the sleeve and one of the rotors so that rotation of the one of the rotors relative to the sleeve in the first rotating direction is prevented, and that rotation of the one of the rotors relative to the sleeve in the second rotating direction is permitted.

The disclosed computer-implemented method may include a magnetic insertable lock component with a magnet-sensing lock housing. By using a magnet within a pin and a magnetic field sensor within the lock housing, the apparatus may accurately detect the state of the lock. In some embodiments, the apparatus may determine the pin is inserted fully into the lock, the pin is inserted partially into the lock, the pin is not inserted in the lock, and/or that a foreign object that is not the pin is inserted into the lock. By using a magnet within the pin to track the state of the lock, the apparatus may improve both the user experience and the security of the lock. Various other methods, systems, and computer-readable media are also disclosed.

Collision alert systems and methods for micromobility vehicles include a proximity sensor, a speed sensor, a warning device, and a controller having a bypass mode and a warning mode. The controller compares the speed of the micromobility vehicle with a predetermined speed threshold, enters the bypass mode when the speed of the micromobility vehicle is less than the predetermined speed threshold, and enters the warning mode when the speed of the micromobility vehicle is greater than the predetermined speed threshold. The controller does not activate the warning device in the bypass mode. In the warning mode, the controller calculates an estimated time until a potential collision with the object, compares the estimated time object with a predetermined time threshold, and generates a collision warning by activating the warning device in response to the estimated time until collision being less than the predetermined time threshold.

Piezoelectric devices mountable on a rigid mechanical structure are described. A piezoelectric device includes one or more piezoelectric elements and one or more supporting structures. A respective supporting structure of the one or more supporting structures has a flat or non-flat surface and is mechanically coupled with a piezoelectric element of the one or more piezoelectric elements so that a mechanical force on the one or more supporting structures is converted into an electrical signal by the one or more piezoelectric elements. A piezoelectric device system including two or more piezoelectric devices and a method for generating electrical signals are also described.

An alarm device for preventing theft of a vehicle having a kickstand support attached to the vehicle having: a housing associated with the kickstand support; a pressure sensing component located associated with the housing and adjacent an end of the kickstand for detecting a force of the kickstand on a ground surface, the pressure sensing component including a surface area for contacting the ground surface when the kickstand is in the deployed position; a controller in electronic communication with the pressure sensor for determining whether the kickstand is in contact with the ground surface based on measurements from the pressure sensing component; a communications module in electronic communication with the controller for wirelessly communicating with a user device. The controller generates an alarm when the kickstand is in the deployed position and determines that the force of the kickstand on the ground has changed by a threshold amount.

A ride-height robust sensor measures shock absorber travel and monitors absolute ride-height in a front and rear shock absorber of a motorcycle regardless of varying cargo weights. Rather than modifying the frame, the sensor is mountable directly to a motorcycle rear shock absorber using a novel upper mount and lower mount. A second sensor is mountable to a front shock absorber using a novel ride-height upper fork bracket and ride-height lower fork bracket. A novel ride-height display module and attendant control module provide a visual display of shock height using a multicolored six LED array. User-customised ride-height and dismount height are activated upon motor ignition and cutoff using a solenoid control module. Components are electronically isolated from the motorcycle ignition system and shock solenoids for accuracy and reliability. The ride-height controller enters sleep mode when not in use and is installable by the user.
